My brother just gave me the OMG Smoke Free starter kit. I have been using it for about a week and it was helping me totally cut back. I was using it earlier today and all of a sudden it isn't working. It is charged and the tip is lighting up. I put a new filter on it but I can get any smoke out of it. I also need to order new filters but I don't trust any of the sites I'm looking at. Where can I order replacement parts??? I don't want to go back to smoking as much as I was and this is the only thing that helped.
